Driver question.

How does one convince Sys. V/AT that we want to write into PHYSICAL memory.
(I/O space for example.)  I want to write into video memory for a graphics
driver at 0xb0000.  I tried:

	char	*base_ptr;

	....stuff....
	base_ptr = gstokv(VIDEOSEL);

But this is wrong.  What is the correct way?
